Easy to reach: Take Subway U6 to "Bahnhof Meidling" (it connects to U2, U3 or U4), then exit "Schedifkaplatz", go left over a little bridge and stay left 100 m. The first on the right is Cothmannstraße. The Tangoloft is in the second building on the right side. Here you can find your best connection: www.vor.at
